This interface is a dual-monitor graphics interface card that supports two VGA, two DVI, or two DP monitors.
NOTE: DisplayPort connections have the highest performance; VGA connections have the lowest.
Identifying monitor connection requirements
The following are various scenarios for connecting monitors. ( See Matching graphics cards to monitor
connectors on page 15 for more information about the different graphics cards):
●
Graphics card with DisplayPort output — If the graphics card has four DisplayPort outputs, you can
connect a monitor to each connector. Use the proper adapters if required.
●
Graphics card with DVI output — If you have a graphics card with two DVI outputs, you can connect a
monitor to each connector. Use the proper adapters if required.
NOTE: Models that have only one DVI port always have a second graphics output option (DisplayPort
or VGA).
Many graphics cards provide more than two monitor outputs but limit you to using only two at a time.
Consult the graphics card documentation or look up information on the card according to the procedure
in Matching graphics cards to monitor connectors on page 15.
On a system with two DVI connections, port number 1 provides the primary display, which is where the
BIOS POST screen appears after a system boot. (Only one card is used during BIOS POST unless you
change the BIOS setting.)
